If you use some common sense and follow the stand builders recommendations, there is very little possiblity of getting injured while using a climber. It isn't hard to attacha climber to the tree, and as soon as you climb aboard, and before you begin ascending the tree, simply attach your safety harness and move it up the tree as you go. After you use a climber a few times, it becomes very easy to set up quickly and quietly, and ascend a tree quickly and quietly, and safely. Climb only trees that are alive and large enough to support your extra weight! There's no more chance, maybe less chance, of an accident with a climber compared to a fixed postion stand!

Yes...while I was hunting with Strut from Missouri he noticed I did not have the correct knot in the rope that goes around the tree. Therefore I would of still fell about 3 feet before the harness could catch me resulting in serious injury.
Other than that I feel pretty safe up there.

PS I forget the name of the knot but it is the adjustable knot that takes out the slack

That's the knot. When it came it the package I was thinking ..why the fancy knot?? Now I know. It's a fancy slip knot to keep one from falling before the harness does it's job. I also must give a thumbs up. I exceed the weight specifications and still feel very safe and comfortable in that. No I'm not fat...just big boned.
